apatite surface closely resembled that of the calcite. This could be due to the precipitation of calcium carbonate on the surface of the apatite. The implication of this observation is that a separation scheme based on the interfacial properties of the individual minerals is not likely to perform satisfactorily for beneficiation of ores.
